Neoadjuvant Study With Pyrotinib and Trastuzumab and Abraxane in Patients With HER2-enriched Breast Cancer

Summary

Breast cancer is kind of highly heterogeneous tumor. The patients with the same stage and with the same treatment regimen, their prognosis varies greatly, mainly due to the different phenotypes of breast cancer and different sensitivities to drug therapy. PMA50 and BluePrint classification divides breast cancer into other inherent subtypes: Luminal A, Luminal B, HER2-enriched (HER2-E) and Basal-like. Previous studies have shown that these patients with inherent subtype of HER2-enriched are more likely to obtain higher pCR after anti-HER2 therapy. And more study and meta analysis had demonstrated the higher pCR is closely related to EFS. The genetic and molecular typing of breast cancer is closely related to the prognosis of breast cancer, so it is imperative to seek a new treatment regimen for precision treatment and maximize the therapeutic benefit of HER2-enriched patients.
